Tension for Pacific Polygut

[Nickswh]

I currently use Luxilon BB Alu Power Rough 16g in the mains and Wilson Extreme Synthetic Gut 16g in the crosses. I string the Lux at 56 and the Syn Gut at 59. I use the Head FXP Prestige MP. I might get a deal with Pacific X for strings and clothes, so they rep gave me a hybrid set of Pacific polygut. It is a 17g Poly (poly force) and a 16L gauge of natural gut (tough gut). I have never played with natural gut and cannot wait to try it out, but what should I string it at? Same tension as the Lux and synthetic? Is natural gut softer and more flexible and should i string it tighter? Thanks alot
